The INRAE site of XYLOBIOTECH is providing to users a confocal laser scanning microscope Zeiss LSM 700, protocols for the preparation of plant samples as well as an expertise in plant cell anatomy.
This equipment together allowed the observation of i) multiple fluorescence associated to colocalization analysis, ii) the 3D and iii) spectral imaging. It also offers possibilities for imaging the living plant cells (FRAP, FLIP, photo activation and conversion) to study intracellular trafficking.
|The microscope is localized at the histocytology lab of UMR BioForA (Integrated Biologyfor the valuation oftree and forest diversity) dedicated to the study of wood formation. The lab has a recognized expertise in histology and microscopic observation adapted to the study of wood formation.

Access to the technical facility
Anyone interested in using a XYLOBIOTECH equipment will require the expertise of the responsible engineer of the technical facility at INRA Orléans who is in charge of the technical management. The responsible engineer will help in designing experiments and will give any advice and practical support for sample preparation and other experimental issues.
Any putative applicant may first contact the responsible engineer to discuss the objectives and conditions of the XYLOBIOTECH service. User’s needs in the frame of technical capacities of the XYLOBIOTECH equipment will be then formalized within a request form. A specific quotation will be written for each user’s demand and management fees will be charged.
Access to the technical facility from Monday to Thursday (8:30am – 6:00pm).
